We use a process that displays pdfs as a binary stream. it has been working fine for a number of years. Suddenly this week we have noticed a few customers calls. When a user of Reader 8 encounters the DisplayBinary link they are asked to save the file as binary.pdf. Once this is done the PDF can be opened and read. Any ideas on why this is occurring and how we might fix it?
However, streaming a PDF as a binary stream is not a recommended way to deliver PDF across the wire. Sending a PDF as a binary stream means the whole PDF needs to get downloaded before it will open. Linking to the PDF will allow the “Fast Web View†to function properly so that the first page will display as soon as all the bytes required for that page have been downloaded. The rest of the file gets downloaded in background while you read.
